brake clunking sound?

[ShionS14]

i have a 98 240sx and just recently i am hearing a noise coming from the driver front thats a popping clunking sound whenever i brake moderately or heavy. it doesnt happen under light braking and it doesnt do it when just pushing on the pedal. i also recently put on solid mount tension rods and thought it might be that but i looked everyting over and it is all tight and normal looking. it sounds like its coming from the brake master cylinder, any insight is greatly appreciatedmatt

also the camber on that wheel is noticeably negative, just thought i would throw that in there
